Oil filter device

The oil filter is used to purify the oil from harmful impurities that have a significant impact on the acceleration of engine parts wear. The quality of the engine oil does not remain constant. The oil receives wear products of parts, soot particles that appear as a result of its combustion in the engine cylinders. It is clogged with resinous substances formed at high temperatures of the parts.

The oil filter is screwed onto the fitting and pressed against the annular shoulder on the cylinder block. The tightness of the connection is ensured by a gasket installed between the filter cover and the block shoulder. Oil enters the filter through channel 9 (see fig. 36) and, having passed the filter element 18, it enters the main oil line of the cylinder block.

The filter has an anti-drainage valve 16, which prevents oil from draining from the system when the engine is stopped, and a bypass valve 21, which is activated when the filter element is clogged and bypasses oil past the filter into the oil line.

The oil is filtered by paper element 18. When changing the engine oil, the filter must be replaced to ensure effective oil filtration.
